| caMonoExp {CalciOMatic} | R Documentation |
The function caMonoExp returns a vector of intracellular
calcium concentration ([Ca^2+]) vs time values t. A dCa jump
occurs at tOn, followed by a monoexponential return to baseline
value Ca0, with time constant tau.
caMonoExp(t = 1, tOn = 1, Ca0 = 0.05, dCa = 0.1, tau = 3)
t |
a vector of time values at which [Ca^2+] is computed (in s) |
tOn |
the time of the [Ca^2+] jump (in s) |
Ca0 |
the baseline [Ca^2+] (in muM) |
dCa |
the [Ca^2+] jump occuring at tOn (in muM) |
tau |
the time constant of the [Ca^2+] monoexponential return to baseline (in s) |
A vector containing the [Ca^2+] values. The vector has the two following attributes:
Time |
a copy of argument t |
tOn |
a copy of argument tOn |

## Simulate a monoexponential calcium transient
Ca <- caMonoExp(t = seq(0,10,0.1),
tOn = 2,
Ca0 = 0.25,
dCa = 1,
tau = 2)
## Plot the calcium transient vs. time
plot(attr(Ca,"Time"),Ca,type="l")
## Add a vertical dashed line at tOn
abline(v = attr(Ca,"tOn"), lty = 2)
